Carnegie Mellon University (CMU) researchers have created a device called Pulp Nonfiction, which looks like a normal sheet of paper, but is able to digitally transfer writing to a computer via a thin conductive layer.
Led by CMU professor Chris Harrison, the researchers placed small electrodes around the edges of the sheet, which was lined with a thin plastic layer that acts as a conductor. Pressing on the page with a pen or finger generates small electrical impulses, and the electrodes interact with one another to map out what's happening in between them. This creates an image that can be transferred to a device and stored digitally.
Harrison believes the paper has applications in everyday note-taking and educational settings, as well as for newspapers and board games.
